One of the objects of the present invention is, to improve the construction of elevators which are built inside thel crib, and y particularly' those which are* called one side elevators, viz.; those built on one side of the drive-way extending through the crib. Y p

The invention has for a further object, to position the leg of the'elevator on one side of the drive-way through the crib, so that the material dumped into the chute leading to the elevator boot, will be delivered in a direction transversely to the direction of movement 'of the lower run of thefelevator, and between the opposite vertical- Vruns of the elevating means. t l I v BuiltV in elevators have been of several forms: one including legs on either side of the crib driveway, the elevating -means traveling down'one leg, across and beneath the driveway and up the other leg, the material to be elevated being dumped into a chute extending across the driveway land longitudinally of the lower run of theelevator; another including spaced legs located on one side of the driveway, the chute for the material being disposed transversely ofthe drive-way and arranged to transfer material to the elevating means-which travels up one leg and down the other; and still another and a much preferred form, comprising a single leg located -on one side of the driveway ofV the crib, the elevating means traveling down one side" of the leg and up the vother side, the chute being arranged transversely of the drive-way and transfering the material-Yin the path lof the elevating means. yI'he elevating means in each of the various types of elevators mentioned, comprises chains and buckets, and therefore, when'the grain, whether `shelled or on the cob, is dumped intothe chute, it is transferred immediately in the Vdirection of movement-of the buckets which cut their Way through the material pickingup a load and conveying it to agdischarge spout at the upper end ofthe leg. The buckets cutting through thegrain destroy quantities of the loosegrain and shell a large portion from off the ears which vis wasted. It is this 'feature of loss which I overcome with the useof my improved elevatorA and its arrangement in the Adriveway of the crib.

` rIhat the invention may be more fully understood, reference is had to the accompanying drawings, in which l Figure l is a front elevation of my improved elevator, partly in section, a portion of the driveway of the crib being shown with a wagon in.` dotted lines .preparatory to dumping material into the chute;

Fig. 2l is an end elevation of Fig. 1,

partly in section, the view looking through the driveway,.with the elevator on the side; y Fig. 3 is an enlarged detail in section showing the bootl construction;

Fig. 4 isa cross-section as the same would appear if taken on the line 4 4 of Fig. 8;

Fig. 5 is a view similar to Fig. 4, showing a modified boot construction.y

Like characters of reference denote corresponding parts throughout the figures.

-l designates the floor of the driveway of va crib, a wagon A being shown in dotted lines to give an idea of the arrangement of the leg of the elevator on one side of the driveway, and the position of the wagonV when dumping the material vto be elevated and stored.

` Extending transversely across the vdriveway and below the floor is a chute 2 into which the material in the wagon' is dumped and by means of which the material is transferred to the boot of the elevator. Also arranged inthe driveway, but to'one side and beneath thefioor of the crib and communicating with the discharge end of the chute is Y -apit y3 in rwhich is located the boot of the elevator leg.

In the form in which the elevator is here shownv it comprises a single leg 4 provided with endless chains 5 adapted to travel up one side of the leg and down the other, passling over sprocket wheels 6 at the upper end of the leg, which are journaled on a shaft 7 having a sprocket wheel 8 adapted to receive power from any suitable source and ing sprocket rings 11, in the boot 9. Connecting the opposite sprocket c hains and suspended therebetween, at suitableV intervals, are buckets 12, which have a scooping action yin the boot 9 and between the` sprocket rings 11, see Fig. 3. As shown in Fig. 3the sprocket rings 11 are of such a*- diameter as to cause a spreading out of the lower runs of the chains 5, so as to enable thebuckets 12 to have a good sweep and scoop the material deposited in the boot 9.

. As shown, the material'discharged fromy the chute 2 will pass through one of the sprocket rings 11 into the path of the buckets 12,y permitting the buckets to scoop up the material, whether loose'grain or corn on the cob without cracking the grain or shelling it. When the material is discharged b'y the Vbuckets at the top. of the legv it is-,received in a chute 13 and transferred to a hopper 1401i -which is swiveled `a suitablel flexible spout 15`by means of acter, the material would be discharged into the side of the elevator legand down upon the buckets, and the pressure ofthe material uponthat being discharged from the chute, together with the pressure of the buckets in another direction, not only cracks the. shelled corn, destroying the same, but

also shells the corn from the-Year, wasting` it. All this is obviated by the use of the present construction. p H y The boot construction shownin Figs-.3 and l include a semi-spherical.shaped receptacle 16 in which the floating @sprocket rings. 11 `are carried, one wall of whichis Vcut away, as at 17, to receive the discharge end ofthe chute 2. l

` InvFig. 5 a modified form vof boot is shown, the remainder of the structure being substantially as seen inFigs. 1 and 2.

In this modified structure the receptacle,V

designated 18, is preferably rectangular in shape, one wall cut awayv to receive the chute 2. In place of the sprocket rings 11, a pair of sprocket wheels-19, suitably spaced apart` are journaledy in -the boot 9, said sprocket wheels being so placed as to spread the lower runs of the chains 5,V the material.

being discharged into the vreceptacle-18 between the sprocket wheels 19 to be scooped up by the buckets. Y

rlhe construction of boot last describedis a very suitable and efficient boot, and'one which may be manufactured at the minimum cost.

Vhat I claim is:
